[Crash-utility] list cgroup from crash

Hi, I am trying to figure out if I can extract the values associated with cgroups from kernel crash dump. I can see "cgorup" is mounted when i issue "mount" command in crash utility. And it shows mount/superblock address. How can I further dig down and print the values inside cgroup fs. Suppose if I want to print "/sys/fs/cgroup/cpu.stat" in the crash utility!? The extension lscgroup / cgget are not working in latest kernels. Regards, Fern
